47 new vulnerabilities affecting 23 devices from 21 manufacturers were disclosed during the DEF CON security conference in August. Smart door locks, padlocks, thermostats, refrigerators, wheelchairs and even solar panel arrays were among the devices that fell to hackers during the event. The vulnerabilities found ranged from poor design decisions like the use of plaintext and hard-coded passwords to coding flaws like buffer overflows and command injection. The conference has so far led to the discovery of 113 critical vulnerabilities across consumer and business IoT products.”]
